COKE-LOADER.

smarter-Tron forming part bf Letters Patent No. 637,427, dated November '21, 1899. Application filed May 25, 1898. Serial No- 68l,689. (N0 model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. STAMM- LER, a citizen of the United States, residing at Johnstown, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvements in Coke-Loaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to new and useful improvements in coke-loaders such as are used for transferring coke from an oven or similar place to railroad-cars or other vehicles for transportation.

It is the object of my invention to provide durable and light-running mechanism for the above purpose and whose capacity is sufficient to receive at one time the entire contents of an ordinary oven, and, further,to so arrange said mechanism as to accommodate a series of ovens located in close proximity to each other. It is finally an important object to provide a loader which will convey material to any one of a series of cars situated upon one or more tracks side by side.

Upon the accompanying two sheets of drawings, forming a part of this specification, the same characters of reference denote like or corresponding parts upon the several figures, and of which- Figure 1 shows a plan view of my loader complete, the coke-ovens being omitted. Fig. 2 is a side elevation of the mechanism shown in Fig. 1, also showing in end elevation two cars in position to be loaded. Fig. 3 is an end elevation as seen from the left of Figs. 1 and 2. Fig. 4 is an enlarged plan view of the coke-car proper, same being partly broken away. Fig. 5 is a central vertical longitudinal section on line 5 5 of Fig. 4. Fig. 6 is a vertical cross-section on line 6 6 of Fig. 2.

My invention is designed to receive its load from any suitable source and need not be confined strictly to use in connection with cokeovens, as stated. I have omitted any illustration of such ovens in the drawings, as their construction is well known to those skilled in the art and forms no part of my invention. In practice, however, the particular ovens used in connection with my novel loaders are provided with a removable door, constituting substantially one end of the same. These doors are opened when the contents of the oven has been coked and it is desirable to remove the same, whereupon by means of rams suitably designed the entire contents of the oven are shoved outward to the loader.

Referring to the characters of reference marked upon the drawings, U indicates the face of the oven, and T a platform in front of same, which is preferably level with the fioor. Q, Q, and Q represent the outer, middle, and inner tracks, respectively, upon which my entire apparatus is mounted. These tracks extend along in front of the entire series of ovens and are located at a given distance below the platform and the oven-floors. At one end of these tracks is located a suitable pit S, into which cars S or other vehicles are placed to receive the load, as will later be more fully described. This pit may be wide enough to accommodate any desired number of tracks and cars, as shown in Fig. 2, and in practice contain posts R to support the outer track.

Upon the tracks Q, Q, and Q is located a carriage which I will designate as N. Said carriage in practice consists of a suitable steel frame mounted on wheels 0 and O, traveling upon the tracks aforesaid. To'each of the driving-wheels O is attached a gear P, which meshes with a pinion mounted upon a longitudinal shaft P, having gear connections 1? with an electric motor P which serves to furnish power and by means of which said carriage is operated upon the track. As will be apparent, the carriage consists of a suitable frame which spans the three tracks before recited and is covered in part by platforms N upon either side. These platforms are provided with hand-railings M upon their outer sides, as will be seen on the drawings. Upon the carriage is mounted cross-rails F, which extend the entire length and form a track upon which a transverse car K operates, as will later be described. The car K is designed to operate upon the'carriage N before mentioned and at a right angle to the movement thereof. It is mounted upon wheels G, j ournaled on axles H, the two forward Wheels being provided with gears H, meshing with a smaller gear H on a cross-shaft I, journaled in the frame, and operates through gears H and H shaft 1 gears H and H shaft I, gears H and H from an electric motor J, secured upon the frame of the car and covered by a platform L, as shown. By means of the above-recited train of mechanism power of reduced speed is applied,.and the car is operated two and fro upon the track for the purpose of transferring the coke, as will be apparent. The car K consists of a suitable frame K, as shown, designed to support a body portion a, having hinged bottom sections A, of which there may be any desired number. These bottom sections are pivoted upon shafts B, secured to the frame K, and each consists of floor portions 1), having a supporting-frame 0, through which the shaft aforesaid passes. As will be observed, (see Fig. 5,) the sections are hung a little to one side of the center, so that they will drop open by gravity when disengaged and permitted to do so. To the under side of the sections are secured brackets D, projecting out on the heavy side of the section and carrying rollers E, which ride upon rails F thereunder. These rails may be of any desired length that is, long enough to reach the first or second car-track in the pit, as desired, or they may be made in sections and adjusted to the proper length. The inner end of these rails F are bent downward at F as shown in Fig. 5, to allow the rollers of the bottom sections to run down, and thus tilt the same in a manner to dump the contents, as will be obvious from an inspection of Fig. 5.

The operation of my invention is as follows: The car K receives its load when in the position shown in Figs. 1 and 2, after which power is applied from the motor P which moves the carriage upon the tracks Q, Q, and Q until the pit is reached containing the cars, when the carriage is stopped, and power is applied from motor J to the car K in a manner to operate the same on its track F, which insures the rollers E traveling on the rails F until the bend F is reached, when said rollers descend, lowering the forward end of the successive sections, thus opening the bottom of the car and gradually and evenly discharging its contents. It will, further, be obvious that, if necessary, I can combine both movements of the car and carriage, thus distributing its load throughout the length of the cars S.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a coke-loader, the combination of a carriage mounted on suitable tracks and provided with driving mechanism, a car mounted on said carriage adapted to operate at a right angle to the movement of the carriage, said car having a bottom composed of a series of hinged doors provided with supporting-rollers, tracks upon which said rollers run, arranged to open and close said doors by the movement of said car, and means for operat ing the same.
